In Animal Crossing: Wild World, Resetti's Headquarters can only be accessed in the Japanese versions of the games, much like Tom Nook coming out at night. To get into his headquarters, the player must hit every rock with a shovel until one cracks. Hit the cracking rock again for a hole to appear, which leads to his home. Some people have put this on many cheat sites, tricking some outside of Japan into trying this but, of course, they are not able to do so. However, in City Folk/Let's Go To The City, you can sometimes access a tunnel on the right side, of the city by the traffic cones, after 8:00 PM. Talking to Resetti then will earn you the silver shovel.

In Animal Crossing: City Folk, rumors went around that have said: "Drinking coffee from The Roost increases the chances of finding Resetti's Headquarters!" Although this is false.

In Animal Crossing: New Leaf, Resetti's Headquarters can be acessed through the manhole cover Public Works Project. It costs 368,000 Bells to build. The manhole can occasionally be found open after 8:00 PM. It is unlocked once the player has quit without saving at least once.
